How do pumps work?

All pumps use basic forces of nature to move a liquid. As the moving pump part (impeller, vane, piston diaphragm,etc.) begins to move, air is pushed out of the way. The movement of air creates a partial vacuum (low pressure) which can be filled up by more air, or in the case of water pumps, water.

How do you explain a pump?


  1. A pump is a device that moves fluids (liquids or gases), or sometimes slurries, by mechanical action, typically converted from electrical energy into hydraulic energy.
  2. Pumps operate by some mechanism (typically reciprocating or rotary), and consume energy to perform mechanical work moving the fluid.

How does a basic water pump work?

These pumps use a piston or a turbine to produce a partial vacuum to draw the water out of the well. The same piston or turbine is then used to increase the pressure of the water. This pressure, in turn, pushes the water out of the pump and down the pipes.

How does an electric pump work?

An electric motor rotates at a relatively constant rate, rotates the pump passes the shaft which is connected with the part protector. Power is channeled to the equipment below through the electrical conductor wires affixed to the tubing, fluid enters the pump in operation.

What is pumping system?

They are used to pump liquids up the tubing and allow gas production to flow up the casing. Gas lift, plunger lift, and surfactant lift all produce gas and liquids up the tubing but pumping systems take mostly liquid up the tubing and gas is separated to casing production.

What are the parts of pump?

The main components in a pump are the casing, impeller, backing plate, shaft and shaft seal, and the motor adapter. Some pumps have the backing plate as part of the casing in which case you would have a removable cover. The shaft seals are a critical part of the pump and selecting the right seal is an important step.

How do pumps create pressure?

When the liquid slows down in the pump casing, some of the kinetic energy is converted to pressure energy. It is the resistance to the pump’s flow that is read on a pressure gauge attached to the discharge line. A pump does not create pressure, it only creates flow. Pressure is a measurement of the resistance to flow.

What is electric pump used for?

The most common applications for electric water pumps for use around the home or yard include: Shallow or deep-well pumps for well systems. Booster pumps to increase water pressure to your fixtures. Submersible utility pumps to remove standing water inside or outdoors.
